Re: 68 BBC alt and power steering bracket questions
Since you are basicly starting from scratch, I would get a serpentine setup from an early 90's 454 pick-up. At least I think they were serpentine. As far as a/c, if you go with vintage air, they can be bought to work on either side and short or long water pump.
